Your skin may be very sensitive to glycolic acid, so Seven Young recommends that you start by using the product once a week to allow your skin to get used to it, then over time you can use the product 2-3 times a week.
On the days you use it, avoid any other products containing AHA and BHA acids, retinol or vitamin C.
1- After cleansing your skin, use a cotton pad and apply an appropriate amount to your skin.
2- Concentrate on congested areas such as the T-zone.
3- Wait for the product to be fully absorbed, then move on to the next step.
4- Preferably use the product at night, and protect your skin from UV rays with a minimum SPF 30 sun cream.
